As the information era proceeds, highly developed digital image processing technique and communication technique make multimedia communication possible, and it is now on the way of progress. video conference have received more attention as an example of multimedia. in this paper we first describe the construction and characteristic of the video conference system and analyze the theory of protocol with itu - t h. 323 recommendation which inculde video and audio codec standard, communication control protocol h. 245. call signalling protocol h. 225, as well as procedures within these protocols define how these components communicate. also an experimental video conferencing system is designed and some relating key technologies are studied, which include multithread programming, transmission technology, mcu technology, qos mechanism and so on. especially, a video codec based on h. 263 recommendation with high fram rate as well as high compression ratio is researched and implemented because of importance of video application, which solves the bad image reconstrction quality problem existed in the most present video systems that adopt h. 261 video compression algorithm. by using these technologies. a video conferencing system is implemented based on lan. the system that the paper provides is easy to implement and the results of exmperiment is good. such system can be widely used in the fields such as business conference, distance education etc. and it is of good practical value
隨著信息時代的前進，數字圖像處理技術和通信技術的高度發展，多媒體通信已成為可能並已初具規模，視頻會議作為它的一個具體應用實例受到普遍關注。本文首先對國際電信聯盟itu - t制定的基於分組交換的多媒體通信h . 323系列建議進行了闡述，其中包括ip網路視頻會議系統的結構組成、視頻傳輸標準、音頻傳輸標準、系統的信息碼流、通信控制協議h . 245和呼叫信令協議h . 225以及會議系統的進行過程。在此基礎上給出了ip視頻會議的實現的整體框架，為系統的軟體實現進行了模塊的劃分和整體設計，分析了各個模塊的功能、作用。 -
